To all whom t may concern: l, x y

Be it lmown that I, VVAUrER` Dnwrrr GozA, a citizen of the UnitedStates, resid-4 ing at Los Angeles, in the countyy of :Los Angeles andState of California, havev invented new andI useful Improvements inBumper Wheel-Locks, of which the vfollowwhen the bumper encounters an.obstacle.

Another objectA of 'this invention is to provide an automobile lockwhich may be locked in an intermediate position so that the wheels willrotate but may not be deviated from a direct'course of travel, thusproviding a lock which will comply with the ordinances in most citiesrequiring that an' automobile may be removed from its standing place incase of iire or accident. l

It is a further object to provide an autovmobile lock which is simple inits construction land maybe positively actuated and locked to producethe above results`. Other objects will appear hereinafter.'f l Theinvention is illustrated (by ywaybf example) in the'accompanyingdrawings, in y swing 1n andout-from the housing which Figure. l isanenlarged .viewfindetail, illustrating one of the locking elements andfurther ydisclosing its'relationto the vehicle frame and'its mountingupon the vehicle. u

trating modiiicationin the jaw construe` v tion and a means Ofanto-maticoperation.

Referring moreparticularly to the drawings, 10-indicates one of theIframe .side members of ya vehicle, upon which is secured avfiXedstandard 11.' This standard lies in thesame horizontal.l plane as the.Ve-

hicle frame and extends forward therefrom. The forwardv'end of the`standard is rectangular in cross sectiony andis adapted to slidably fita lock housing 12; this housingr in form isintegral with the cross lbar13 of the bumper and includesthe locking mechaf nism with which thepresent invention is concerned.

@The 100k mechanism s disclosed in Fig.

k1v` of the'drawings comprises va lhorizontal slidable actuatingbolt 14,which is fitted at its forward endwith a pivot pin 15adapteditopivotally engage a-.link 16. Thislink extends toward the bumper and isheldin pivotalengagement with a bell crank 17 byffmeans of a pivot pin1,8, the bell crank 17 being mounted for oscillating movement upon ashaft 19 incorporated within the bumper construction. The oppositeA lookof the bell crank extends forwardly and engagesaj aw link 20 by means ofa pivot pin 21.' This jaw link is in turnf secured by' pivot pin 2 2 toa llockingv jaw 23, held upon a pin 24:, which i'sfdisposed insubstantially horizontal alinement with the center of one of'a pairoffrontjwheels2).y The locking mechanism` as described is entirely housedwithinthehousing and a 'portion of the locking .jaw however, is.permitted to engage the" inner side of the vehicle tire.-

and to l'transverse section .of they bumper. The 'i The outer lsidelofthe vehicle tire is en` gaged byv a bumper'horn 26, which is arcufy atelin shape and is designed to substantially conform to the' sectionalcontourof the tire.

Reference being had to Fig. '1 of the drawing, will be seenv thatthestandard 11 and the 'lock ltare` separately mounted within the bumperhousing andlareprovided with a` lost motion mechanism'which will permitthe "bumper to be mounted upon vehicles of various 'dc/, KSgI1`Svwithout a'tlterationk of the parts. involved. .l Thise mechanismconsists of a double lacting pawl '27, which is pivotally secured 'by`aV pin 28 in a'longitudinally extending slide 29 formed along the centerof the lock bolt 14).] The pawl .extendsrear- Y wardly from "thisslideand when' the 'two parts are adjacent veach rother will extend into asimilar slide 30, formed in the forward end of the standard-11. trip pinr31 j bridges the slide and is adapted under some circumstances toengage a tooth 39. formed upon the under side of the pawl. The back ofthe pawl is formed with cam faces 33 and 34, which are disposed atopposite ends of the pawl and alternately encounter actuating bars 35and 36 respectively, by which vthe mechanism vis positively actuatedwithout the use of springs.

Reference being had lto Fig. 3, it will be seen that the standard ll isformed with an extension corresponding to the lock bolt 14, andt'hatmovement of the bumper in the olirection Aindicated by the 'arrow-kawill cause the entire standard to advance through the lock housing,in this mannery directly and instantly actuating the lock mechanism. Inorder to show means for locking the bumper in a' desired position, aseries of three transverse holes 37 are formed through the stand ard andadapted to be brought to successively register with complementary holesformed throughthe opposite walls of the lock housing. Thisl arrangementis provided to permit a lock bolt y38 to eXtend ofthe front wheels.

through the housing wall and one of these holes to lock the bumper andthe locking jaw in: a desired position.A A padlock 39 is provided toholdtheV bolt in its place This arrangement, however, may be changed and'other and more convenient 'locking means substituted without departingfrom the spirit ofy the invention.r

ln operation the bumperis normally .positioned as shown in Fig. 4: ofthe drawings, and lpreferably is spaced a distance of ap. proximately 2inches ahead oi the periphery Y When in Jthis position the lock housingis drawn to its foremost position in relationV tothe vbolt 171, this inturn exerting a pull on the link 16 which is transmitted through thebell "crank 17 to 'the lock jaw 23 and draws the locking jaw toward thebumper and away from vehicle wheel. lThis condition is identical in boththe vpreferred and modified form' of the invention as disclosed in Figs.l and 3 respectively. vHowever, in the mechanism disclosed in Fig. l,the actuating lbar 35., will pass over the cam face 33 ,upon the pawl527 and act toraise the cam'lto release the tooth 32 of `the ,pawl fromlengaging with the pin 31, j after which -the Abumper may be drawn aheadas far as desired. When an' obstacle is encountered .by the bumper, theforce will be transmitted to move the bumper rearwardly and slide italong the 'uprights ll. In' .the construction illustrated in F ig. l,considerable movement "will take place before k the locking mechanismwill be actuated. This'is due to lthe `fact that the upright 11 has-been drawnoutof engagement with the locking Vvbolt lll and stands inspaced relation thereto. As the bumper moves rearwardly the adjacentends of the upright and bolt 14 williabut fagainst each other, andthereafter through the link 2O to swing 'the locking jaw 23 toward thetire as Vthe bumper'itself Xapproaches the'tire, and as the operationpro.- ceeds the locking jaw 23 vand the horn of the bumper 2b' willco-act to positively grip the opposite 'sides `of 'the tire and brakethe wheel against rotation, thus effectively applying an emergency brakewhen desired.

The action to permanently lock the wheels by means of 'the bol't '38andthe Vlock 39 will be 'the same as th-'at previously described, Vasthe bumper will be manuallyfforced4 von to the standards '1l and.lcaused `to `grip the wheel by means of its jaws. l j

vvWhen it yis/desi'red 'to immovably lock the wheel, the boltBS ispositioned through the When `it is desired to is ypassed 'through theVmiddle opening 37 i and will maintain the jaws in a ,positionto limitthe swinging movement ofthe wheels.

In the modiiied form illustrated in Fig. 5 a'ws '40 and il are formedwith actuating extensions 'adapted to be encountered by the tire asF'the bumper moves rearwardly. Yand this willhcausethe jaws toautomatically bindthe tire without the use of mechanism.

It will thus be seen that the combined bumper and lock here disclosed,will act in a simple manner to retard the movement of the vehicle inemergency cases, conne theV vehicle toa straight path oftravel when* sodesired,'or positively lock :the vehicle against movement, by means of apositively and easily operated mechanism.

WV 'ile l have shown ytheprei'erred construction of my lock as now knownto me, it will be understood that various changes in lio thecombination, construction and arrangement of parts may be made by thoseskilled inthe art, without departing from the spirit of my invention.-
